HOWARD M. DUDLEY, OF PHILADELPHIA, PENNSYLVANIA.

DYEING-MACHINE.

Specification of Letters Iatent.

Patented Mar. 5, 1918.

Application filed December 22, 1916. Serial No. 138,309.

To all whom it may concern:

Be it known that I, HOWARD M. DUDLEY, a citizen of the United States,and a resident of Philadelphia, in the county of Philadelphia and Stateof Pennsylvania, have invented certain new and useful Improve-- ments inDyeing-Machines, of which the following is a specification.

My invention relates to a dyeing machine and refers particularly to amachine adapted tor the dyeing of textile libers compressed within adyeing chamber the dyeing being accomplished by the forced passage ofthe dye liquor through the fiber mass.

Among the objects of my invention is a dyeing machine particularlysuitable for the dyeing of warps in the ball, whereby the condition ofthe fiber may be accurately and readily judged at any stage of thetreatment without opening the dyeing chamber and whereby even resultsmay be obtained without disturbing the fiber to be dyed.

Other objects of my invention will be evident upon a consideration of myspecifications and claims.

I have found that the even or uneven dyeing results obtained in amachine of this general character depends largely upon the particularshape of the openings through which the dye liquor enters the fibermass, and that unevenness can be prevented by the use of openings of aparticular shape, the conformation of which enables the liquor to spreaditself through the fiber mass without the formation of channels of flow.

l have further found that this desirable result can be obtained if suchopenings are oi. an elongated form, diverging upwardly into the dyeingchamber or of a double di- 'erging conformation, diverging both upwardly into the dyeing chamber and downwardly into the source of dyeliquor, and furthen that the evenness of the dyeing may be furtherenhanced by causing the dye liquor to pass through a chamber containingrods of particular formation and arrangement before passing into thedyeing ehai'nber.

Related forms of my device are shown in the accompanying drawings, inwhich simi lar parts are designated by similar numorals.

Figure 1 is a side view of one form of my invention, partly broken awayto disclose a portion in cross-section.

Fig. 2 is a cross-section through the line 2--2 of Fig. 1.

Fig. 3 is an enlarged side View of two of the rods introduced into theliquor supply chamber.

Fig. l is a broken side view of one modification of mydevicc showing anupper and a lower arrangement of the rods in the liquor supply chamber.

Fig. 5 is a cross-section of the pump chamber showing the rods extendingdownwardly therein.

The outer portion of the dyeing machine comprises the cylindrical shell7 and the cylindrical shell 8, fixedly attached to each other by thebolts 9, 9; the conical shaped shell 10 fixedly attached. to the shell 8by the bolts 11, 11 and the centrifugal pump 12 fixedly attached to theshell 10 by the bolts 13, 13. A foraminons plate is situated be tweenthe shells 7 and 8 integral with the wall oi the shell 8. The foraminousplate is of a grate construction comprising the bars 16, 16. The bars16, 16 taper upwardly and downwardly from their center lines, formingdiverged openings 14L, 141 between them for the passage of liquor.

The machine is provided with a removable annular foraminous plate 17,the construction of which is similar to the foraminous plate 14.

An annular angle-shaped member 18, is slidable within the shell 7,capable of abutment upon the plate 17 and maintained in any desiredposition by means of the thumbscrews 19, 19, which thread within theshoulders 20. 20 fixedly attached to the shell 7.

A series of rods 21. 21 are positioned in the interior portion oi theshell 10, the rods ex tending from the top to the bottom thereof,

their upper and lower ends being tapered.

These rods are maintained in their position by the supportingdiamond-shaped bars 41.. d1. i

In the modification shown in Figul. the i rods 23., 21 are replaced byrods 22, 22 extending downwardly from the top oi the chamber within theshell 10, and rods 23, 23 extending upwardly from the bottom of thechamber within the shell 10, the two series of rods being in alinement wch other.

In the modification shown in Fi 5 the rods 23, are replaced by rods291-, 24-. which extend downwardly beyond the lower portion of thechamber within the shell 10 into the chamber of the rotary pump 12.

A perforated steam pipe 25 is introduced into the chamber formed by theshell 8,

In orderto facilitate reference to the various chambers, they willhereafter be re ferred to as the top chamber 26, the dyeing chamber 27,the liquor supply chamber 28, the rod chamber 29, and the pump chamber30.

An over-flow pipe 31 connects the top chamber 26 with the centrifugalpump 12 to allow of continuous flow of the liquor up- 7 wardly throughthe machine.

A pipe 32 connects the pump 12, with a liquor supply tank, not shown,the pipe 32 carrying the valve 33.

A pipe 34%, 35 extends from within the liquor supply chamber 28 to apoint above the top chamber 26, and carries a thermometer 36 forregistering the temperature passing through the pipe 34:, 35.

A sample dyeing machine 37, exactly similar to the above describeddyeing machine, except in smaller proportions, is connected to theliquor supply chamber 28 by the pipe 38 and to the top chamber by thepipe 39. The sample material in the machine 37 is examined by removingthe top 4:0 which.

sample device 37. The pump 12 is started and the valve 33 opened,allowing the liquor to flow through the pipe 32 into the pump 12, bywhich it is forced upwardly through the pump chamber 30, the rod chamber29,

the liquor supply chamber 28,.and the goods in the dyeing chamber 27,into the top member 26. When the liquor has reached a height to allowits flow through the pipe 31 back into the pump 12, the valve 33 isclosed and the liquor is forced continuously through the device as abovestated.

. From time to time, the valve 42 is closed,

the top dO is removed for-the, purpose of examining the condition of thedyeing operat-ion, andis then replaced, the valve 42 is opened and thedyeing continued until ithas reached a satisfactory condition.

in is evident that durin "this operation neonate the liquor is forcedupwardly between the rods 21, 21, the up er ends of which cause it tospread out upon leaving the space between the rods, the flow of theliquor thus exerting an upwardly divergent force. As the liquor leavesthe spaces in the foraminous plate 16, the divergent edges of the seaerating members causes it to spread out and to impinge upon thematerial in the dyeing chamber 27 in a practically uniform manner, andthat the continuing of this flow will force the liquor throughout themass of goods, and willpreventthe formation of channels through thegoods. As the plate 17 is the same as plate 16, the pressure will bemaintained in the dyeing chamber 27, and the liquor will be compelled topenetrate the goods inwardly toward each of the openings in order toescape. V
